BACKGROUND TECHNICAL FIELD

The disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a method and a device for power control in wireless communication.

RELATED ART

Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance requirements on systems. In order to meet different performance requirements of various application scenarios, in the design of Rel-15 New Radio (NR), beamforming is widely used to improve transmission performance. In Rel-16 NR systems, in order to further improve transmission performance and reduce transmission latency, the RAN #81 plenary session proposed a Study Item (SI) of physical layer enhancement for Ultra-Reliable and Low Latency Communication (NR URLLC). In this subject, the performance enhancement for an uplink PUSCH will be one of important research subjects.

SUMMARY

In Rel-15 NR systems, a Physical Uplink Shared Channel (PUSCH) already can support slot-level repetition transmissions to improve transmission performance, that is, one Transmission Block (TB) can be repeatedly transmitted in multiple slots to realize combined gains. In Rel-16, in order to further reduce latency, a PUSCH and a Physical Uplink Control Channel (PUCCH) will be repeatedly transmitted between multiple mini-slots to achieve an effect of reducing latency.

In Rel-16 and future mobile communication systems, no matter a base station or a terminal equipment will be configured with multiple panels, and a transmitting terminal will transmit multiple radio signals on multiple panels to achieve gains brought by beamforming. The above repetition transmissions of PUSCH and PUCCH can also be performed between multiple panels. However, in this scenario, power control methods for the radio signals repeatedly transmitted on multiple panels need to be redesigned.

One simple solution for the above problems is as follows: when multiple panels correspond to multiple Beam Pair Links (BPLs), transmit power values for the multiple panels can be adjusted separately. However, this method has high demands on the Radio Frequency (RF) and Power Amplifier (PA) of a transmitting terminal, and it is unnecessary. In view of the above problems, the disclosure provides a solution. It should be noted that, if no conflict is incurred, the embodiments of the first node of the disclosure and the characteristics in the embodiments may be applied to the base station, meanwhile the embodiments of the second node of the disclosure and the characteristics in the embodiments may be applied to the terminal equipment.

Embodiment 3

Embodiment 3 illustrates a diagram of an embodiment of a radio protocol architecture of a user plane and a control plane according to the disclosure, as shown in FIG. 3.

FIG. 3 is a diagram illustrating an embodiment of a radio protocol architecture of a user plane and a control plane. In FIG. 3, the radio protocol architecture of a first node and a second node is represented by three layers, which are a Layer 1, a Layer 2 and a Layer 3 respectively. The Layer 1 (L1 layer) 301 is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as the PHY 301. The Layer 2 (L2 layer) 305 is above the PHY 301, and is responsible for the link between the first node and the second node over the PHY 301.

In the user plane, the L2 layer 305 includes a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303, and a Packet Data Convergence Protocol (PDCP) sublayer 304, which are terminated at the eNB on the network side. Although not shown in FIG. 3, the first node may include several higher layers above the L2 layer 305, including a network layer (i.e. IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end (i.e. a peer UE, a server, etc.) of the connection. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for higher-layer packets so as to reduce radio transmission overheads. The PDCP sublayer 304 provides security by encrypting packets and provides support for UE handover between second nodes. The RLC sublayer 303 provides segmentation and reassembling of higher-layer packets, retransmission of lost packets, and reordering of lost packets to as to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical channels and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (i.e., resource blocks) in one cell among first nodes. The MAC sublayer 302 is also in charge of HARQ operations. In the control plane, the radio protocol architecture of the first node and the second node is almost the same as the radio protocol architecture in the user plane on the PHY 301 and the L2 layer 305, with the exception that there is no header compression function for the control plane. The control plane also includes a Radio Resource Control (RRC) sublayer 306 in the layer 3 (L3). The RRC sublayer 306 is responsible for acquiring radio resources (i.e. radio bearers) and configuring lower layers using an RRC signaling between the first node and the second node.

Embodiment 4

Embodiment 4 illustrates a diagram of a first communication equipment and a second communication equipment according to the disclosure, as shown in FIG. 4. FIG. 4 is a block diagram of a first communication equipment 450 and a second communication equipment 410 that are in communication with each other in an access network.

The first communication equipment 450 includes a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter/receiver 454 and an antenna 452.

The second communication equipment 410 includes a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter/receiver 418 and an antenna 420.

In a transmission from the second communication equipment 410 to the first communication equipment 450, at the second communication equipment 410, a higher-layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 provides functions of Layer 2. In the transmission from the second communication equipment 410 to the first communication equipment 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between a logical channel and a transport channel, and a radio resource allocation for the first communication equipment 450 based on various priority metrics. The controller/processor 475 is also in charge of retransmission of lost packets, and signalings to the first communication equipment 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for Layer 1 (that is, PHY). The transmitting processor 416 performs encoding and interleaving so as to ensure FEC (Forward Error Correction) at the second communication equipment 410 and mappings to signal clusters corresponding to different modulation schemes (i.e., BPSK, QPSK, M-PSK M-QAM, etc.). The multi-antenna transmitting processor 471 processes the encoded and modulated symbols with digital spatial precoding (including precoding based on codebook and precoding based on non-codebook) and beamforming to generate one or more spatial streams. The transmitting processor 416 subsequently maps each spatial stream into a subcarrier to be multiplexed with a reference signal (i.e., pilot) in time domain and/or frequency domain, and then processes it with Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. Then, the multi-antenna transmitting processor 471 processes the time-domain multicarrier symbol streams with a transmitting analog precoding/beamforming operation. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency stream and then provides it to different antennas 420.

In a transmission from the second communication equipment 410 to the first communication equipment 450, at the first communication equipment 450, each receiver 454 receives a signal via the corresponding antenna 452. Each receiver 454 recovers the information modulated to the RF carrier and converts the radio frequency stream into a baseband multicarrier symbol stream to provide to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform various signal processing functions of Layer 1. The multi-antenna receiving processor 458 processes the baseband multicarrier symbol stream coming from the receiver 454 with a receiving analog precoding/beamforming operation. The receiving processor 458 converts the baseband multicarrier symbol stream subjected to the receiving analog precoding/beamforming operation from time domain into frequency domain using FFT (Fast Fourier Transform). In frequency domain, a physical layer data signal and a reference signal are demultiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any spatial stream targeting the UE 450. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then, the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal on the physical channel transmitted by the second communication equipment 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of Layer 2. The controller/processor 459 may be connected to the memory 460 that stores program codes and data. The memory 460 may be called a computer readable media. In the transmission from the second communication equipment 410 to the first communication equipment 450, the controller/processor 459 provides multiplexing between the transport channel and the logical channel, packet reassembling, decryption, header decompression, and control signal processing so as to recover the higher-layer packet coming from the core network. The higher-layer packet is then provided to all protocol layers above Layer 2, or various control signals can be provided to Layer 3 for processing.

In a transmission from the first communication equipment 450 to the second communication equipment 410, at the first communication equipment 450, the data source 467 provides a higher-layer packet to the controller/processor 459. The data source 467 illustrates all protocol layers above the L2 layer. Similar as the transmitting function of the second communication equipment 410 described in the transmission from the second communication equipment 410 to the first communication equipment 450, the controller/processor 459 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation so as to provide the functions of L2 layer used for the control plane and user plane. The controller/processor 459 is also in charge of retransmission of lost packets, and signalings to the second communication equipment 410. The transmitting processor 468 conducts modulation mapping and channel encoding processing; the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding (including precoding based on codebook and precoding based on non-codebook) and beaming processing; and subsequently, the transmitting processor 468 modulates the generated spatial streams into a multicarrier/single-carrier symbol stream, which is subjected to an analog precoding/beamforming operation in the multi-antenna transmitting processor 457 and then is provided to different antennas 452 via the transmitter 454. Each transmitter 452 first converts the baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream and then provides the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication equipment 450 to the second communication equipment 410, the function of the second communication equipment 410 is similar as the receiving function of the first communication equipment 450 described in the transmission from second communication equipment 410 to the first communication equipment 450. Each receiver 418 receives a radio frequency signal via the corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 together provide functions of Layer 1. The controller/processor 475 provides functions of Layer 2. The controller/processor 475 may be connected to the memory 476 that stores program codes and data. The memory 476 may be called a computer readable media. In the transmission from the first communication equipment 450 to the second communication equipment 410, the controller/processor 475 provides de-multiplexing between the transport channel and the logical channel, packet reassembling, decryption, header decompression, and control signal processing so as to recover higher-layer packets coming from the UE 450.
